Objective: To evaluate the effectiveness of micronized natural progesterone administered orally and intravenously administered fenoterol in the treatment of patients with a diagnosis of preterm labor. Method: The type of therapeutic trial in patients attended at the Hospital Universitario de Caracas. Results: 15 patients in the progesterone study showed satisfactory results (X² = 155.837 df = 18); the control group, 13 patients with satisfactory results (X² = 133.093 df = 18). The absolute effectiveness in the study group was 0.68 against 0.59 in the control group (X² = 0.393 df = 1, P < 0.531). Conclusions: Treatment with micronized natural progesterone and fenoterol proved inhibitory uterine dynamics from the second hour of starting treatment preventing its progress toward labor by 90 %. The micronized natural progesterone is effective in the treatment of preterm labor and should be considered as an alternative therapeutic use.
